-To all uwm it may concern:

HEAD, a citizen of the United States, and

resident of Chicago, in the county ofCook and State of Illinois,haveinvented certain neiv and useful Improvements in Duplex Fnvelops, of which the following is a specification, reference being had `therein to the accompanying drawing.

My present invention refers to a double compartment envelop or package-intended to contain contribution money for different purposes, and especially adapted vfor use by missionary and benevolent societies and organizations Where it is desired to apportion the moneys collected to various objects. The object of the invention is toprovidea simple, economical, and efficient device of the class described, and which will furnish tivo or more pouches or iiiclosures for thereception of contributions, which inelosures are effectively bound and closed so that'tlieir contents may not be dissipated, and which inclosures further are easily separable from each other so that a perfectly sealed coinpartment, inclosure, or envelop may lbe handed to each of the objects for which the offerings are being made. The invention, therefore, may be said to consist essentially in the construction, arrangement and cornbination of parts, substantially as will be hereinafter described and then more particularly pointed out in the annexed clauses of claim. y y i In the accompanyingdravving illustrating my invention: y

Figure 1 is a rectangularblank Whicli'is to be folded on predetermined lines to form my improved duplex envelop;

Fig. 2 is a view of the same Wlienpartially v folded;

Fig-2, butlviewed from-tlie'otlier-side so a's lto indica-te the gummed-ed-ges ofl the flaps of thevpouch'es;

iFiig. gis faper'speetivelveavfof one of fthe sealed and .bound edges ror3cempartments' off "the envelop #when vsevered 'from f the other Fig. 'S-is a cross-section on tlie line 8, 8 of Fig. 5;

Fig. 9 is a cross-section on the line 9, 9 of Fig. 5.

Similar characters of reference designate corresponding parts throughout the dilferent figures of the drawing.

The blank out ot' which my present improved duplex envelop is made, is preferably rectangular in form, as shown in plan view in Fig. l, being of'greater or less size, and With its linear dimensions variable Within Wide limits, provided only'it is susceptible of being'folded according to the general plan of my invention so as to furnish a pair of envelops, pouches, inclosures, or compartments, having a general triangular shape and Aadapted to belleft as a single duplex yunit or severed into two independent single units accordingly as Ythe accounting methods for `the Vcollections Vmay render necessary.

'This-main blankis creased vfirst on the trans- *verse'parallellines 3, 3 which are at a short vdistance from the ends 7, so asIto provide the narrow flaps or sealing covers S which are preferably-gummed at 12.

The next fold'Wil-l be on diagonal lines 5,

*5 Vrunningfromcorrespondingends of the lines 3,3 to vthe opposite end of the central transversefline 2,-'vvhicli is the median line of Uthe nenvelop-and onwhich the next fold is vmade fory t'lie'pu'rpose' of preliminarily formino thetwo ouelies. Referrinor for exam ile 'to Figs@ and-53,'it Will be seen how the folds are made von these diagonal lines 5, 5 to cause fthe triangular sections 9, 9 to lie flat upon the Ytri-angular sections 10, 10 with the flaps '8, 8 creased but not I vet folded over, as the 'folding andsealiiigofthe flaps 8, 8 will take place only afterfthe pouches liavebeen filled Vin use'. "When the Ytriangular sections 9, 9 lie supe'rposed upon the triangular sections '10, '10, as vievved'from one side Fig. 2 and fromxtlie other side in Fig. 6, it will be seen thattlie,edgesfG of the triangular-sections 9,

wvliiehaarelgummedat 13, will lie upon't-'lie triangular sections-"10, 10 closely contiguous to the median line 2 of the envelop and the adhesive at 13 may be caused to securely fasten the edges G, 6 to the sections 10 near the line 2 whereby two receptacles of triangular shape will be formed, which recep-v tacles can be placed so that one will lie onor opposite to the other by merely bendiii the blank along the median line 2 in the siape indicated in Fig. 3 -wliere I present the duplex pouches with their fiaps 8 raised over the mouths of these pouches in readiness to receive the insertion of the collection moneys therein either inone or both of the pouches, as desired. After either pouch is lled the Vflap 8 can be sealed down over the section 10, thereby covering the edge 1 and the mouth,

and being adhesively attached to the section '10, the pouch, either one or both of them as the case may be, will be effectively closed.

'Thus we have the two pouches which are entirely independent ot' each other, except that they are attached together in a single unitary structure. The, ends of the flaps 8V over the adjoining portion of the envelop.

.When the triangular binder is not used, or

before it is used, the envelop will, after the iiap 8 has been sealed down to cover the Ymouth of the pouch, appear as indicated in Fig. 4, but whenthe binder 4 is sealed in place. it will be turned over the edge, as indicated in Fig. 5, and this binder may obviously be used for the purpose of completing the sealing of each single pouch or for the purpose of sealing together the two pouches, 'in whichcase one ot' the binders will overlap and be sealed to the other pouch, that-is to say, these triangular binders 4 may simply complete the sealing of individual,pouches by being turned over and sealed to its own pouch, or one ofl them may be sealed to its own pouch and the otherturned over the edge of the adjoining pouch and sealed thereto, in which case we will have two pouches or compartments completely inclosed and effectively sealed in one substantial structure which can be handled in any desired manner without any commingling of their contents and without any dissevering under ordinary uses of the two pouches. -When, however, it is desired to separate these pouches in order that they may go to dii'erent treasurersor societies, then by the aid of aknife or paper cutter the two inclosures or compartments may be readily dissevered from each other by running the knife be- Vtween the two bouches and severing them along the split back which is the median line 2, which is immediately between the two gummed edges 13 and also, if one of the triangular binders has been sealed to unite together the two pouches, severing likewise the Vsaid triangular binder so` that tlie'two triangular inclosures `are separated from each other and made entirely independent. vOne of these independent inclosures Vafter being K severed from the other is shown in'perspec- Vtive viewinFig. 7.

l lay particular stress and emphasis therefore upon the ability-of this device to be cut along its split back intotwo separate devices, and also I wish' to emphasize the triangular binding corner which enables the front edges 'of the triangular pouches to be connected to- VVVgether securely and strongly after both .pouches have been filled and sealed. This makes the envelop much more compact than if the device were allowed to retain the general forinand position shown in'Figs. 2 or 6 with their flaps sealed but without having the outer portionsv of the triangular `pouches connected, for -when they are connected the device is Vsimpler' and better in'every way.

AFurther with the splity backit possible for one side ot the envelop to be used unsealed land the other sealed, which serves as a time saver to the treasurer anda constant` ie- :minder tothe contributor. NVith two pouches arranged and related in the manner that I havefde'scribed, it will be found impossible for coins to slip from o neside` to the other throughany defective gumming when the device is finally sealed or bound. lVith the" double sealingY device, it is evident thatY the envelop may beY used for either side ori'or both sides even'when one side contains no coin. vWhen the envelop is'sealed and bound,

there is no disclosure of the contents infany 'way. v v v Y It is further to benoted tliatfthefaceof kone or both of the triangular inclosures, asv

also the flaps, and in fact all vparts ot' the envelop may be covered with'suitable printed blanks or other designations to diiierentiate the compartments fromV each other and to representby dates and numbers theV times for making the collection, Vthe number ofthe contributor, and other necessary data for the proper accounting of thecontributions and with the lists ot' the objects" for which the contributions 1 are supplied, scripture texts, and other matter Vwhich may be useful or desirable with envelops of this character,

of the blank and the wayin Vwhich they Vare combined and related for the purpose of performing the functions as specified, may be made in the same and I reserve the liberty of modifying and adjusting these features within Wide limits.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a duplex envelop, a blank havin its ends folded to provide iiaps having at t ieir ends binding corners, and being also folded on lines running from the top of the flaps to the middle point of the bottom of the blank, the whole heilig sealed to furnish two separable separate inclosures.

2. In a duplex envelop, a rectangular blank having its ends folded to provide flaps and being also folded on diagonal lines running from the flaps to a middle line on which it is likewise folded, the whole being sealed so as to provide a duplex unit which furnishes two separate inclosures that are easily separable from each other.

3. In a duplex envelop, a rectangular blank having its opposite ends folded to provide adhesive flaps, the ends of which have foldable corners to provide binding flaps and the blank being also folded on a central line and on diagonal lines running from one end of the central line to the flap creases, the

Copies of this patent may be obtained for whole being folded to provide two separate pouches or compartments that can subsst in a unitary structure or be separable into two distinct individual envelops.

4. In a device of the class described, a rectangular blank which is foldable on a central line into two sections, each one of which is foldable into a triangular pouch, each pouch having a iiap and a triangular binder, and the whole device being capable of being severed into two individual compartments or kept as a single unitary structure.

5. In an envelop device of the character described, a blank foldable on the central line to provide two sections, each of which is foldable into the form of a triangular pouch, said pouches being connected alongside said central line which is severable to divide the device into two independent pouches.

6. In a duplex envelop, a pair of triangular compartments formed integral with each other and connected at a central severable line, said compartments being provided with individual sealing aps having each a folded binding corner whereby7 the edges of the compartments may be sealed together at a point opposite to the severable connection.

In testimony whereof I hereunto afx my signature.
